About the Airtac GAFC Air Service Unit GAFC40010ALNW
The GAFC40010ALNW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air enters the 3/8" port, gets filtered to 5 um and regulated to a lower 0.15-0.4 MPa (20-58 psi) band, then the lubricator meters oil mist into the flow last. This lower-pressure version suits delicate circuits where a 0.9 MPa ceiling would be excessive.
With a 100 cc condensate bowl and a separate 185 cc oil reservoir, the 1810 g unit is built for sustained operation on a machine header. The automatic drain clears water without an operator, and the 5 um element traps finer particles than the standard 40 um grade. No gauge is supplied, so the 1/4" gauge connection on the body is where a pressure readout would be added.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC40010ALNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the lower 0.4 MPa ceiling prevents over-pressurizing sensitive actuators. The 5 um element keeps fine particles out of valve pilots.
Wet plant air headers
Mount on a machine header in a humid plant where condensate is constant. The automatic drain clears water from the 100 cc bowl without an operator, and the 185 cc oil bowl keeps lubrication steady.
Instrument air skids
Use on a test bench or instrument air skid where regulated low pressure is needed for calibration fixtures. The 5 um element and lower pressure range protect delicate gauges and orifices.
Is the Airtac GAFC Air Service Unit GAFC40010ALNW the Right Air-Prep Unit?
Choose the GAFC40010ALNW when your circuit runs below 0.4 MPa and needs fine filtration. The L type tops out at 0.4 MPa, so if the machine may ever need more pressure, step to a standard S type instead. The 5 um element suits precision valves or instrument air but will need service sooner than a 40 um element. The automatic drain is the right call for unattended lines or wet compressed air. The PC bowl is the standard build; confirm it fits your environment, as the catalogue gives no material-specific ratings. The PT thread comes with a gauge scale in MPa/psi if you add a gauge later. The two units are orderable separately as the GAFR400-10 filter & regulator and the GAL400-10 lubricator. A 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC40010ALNW FAQ
The GAFC40010ALNW operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures. The drain bowl holds 100 cc and the oil bowl 185 cc. It weighs 1810 g and uses ISO VG 32 lubricant. The filter grade is 5 um.
The N after the port code means no gauge is supplied; the 1/4" gauge connection is on the body if you add one. The L type is the lower-pressure version, regulating from 0.15 to 0.4 MPa (20-58 psi) instead of the standard 0.9 MPa. This suits circuits that must never see higher pressure.
